tAntr-srmnn FRAME.

To all whom it may concern: 1 v r Be it known that I, VIoroR S. PEARLMAN, a citizen-of the United States, and a resident of Chicago, in the county 'of Cook and State of Illinois, have invented certain new and useful Improvements in Lamp- Shade Frames, ofwhichthe following is a specification.

' My inventionrelates to'lamp shade frames" particularly to skeleton frames for supporting ornamental fabric or other material.

Lamp shades, particularly those for ornamental uses, are usually constructed by forming a skeleton supporting frame of wire and securing thereon the ornamental fabric or other material. The frame usually has an upper marginal ring of wire with spokes radiating inwardly and secured to an inner supporting ring usually of wire, this inner ring being of a diameter to enter a shade holder to be received by the holder screws. This is a very impractical and inefficient ar rangement for it is a tedious, disagreeable and laborious task to get the ring properly into the holder and in such engagement with the supporting screws that the shade will be rigid and secure and will hang straight. The object of my invention is to improve on such prior construction and to provide a frame which can be more readily and accurately secured in the ordinary forms of holders. This I accomplish by providing an inner supporting ring of special sheet metal construction, the ring flaring upwardly and being provided with holes or slots in its sides for receiving the inner ends of the frame spokes to which the ring is then secured as by bending of the spoke ends and soldering.

In the accompanying drawings I have shown a frame embodying my invention. In these drawings I Figure 1 is a perspective view of a frame,

Fig. 2 is a diametral vertical sectional view, and

Fig. 3 is a diametral sectional View of a modified arrangement. v

The frame shown comprises upper and lower marginal rings 5 and 6 ofwire, these rings being connected by vertical ribs 7 the upper ends of which are deflected radially with reference to the upper ring to form spokes 8 which terminate equidistant from the frame ring center.

supporting. inner ring 9. is providedwhich has the. lower cylindrical section 10 :and theupper flaring section 11. In the lower cylindrical section. transverse slots; 12: are .provlded for receiving the lIlIlGlTBIldSOf the spokes 8. The supporting ring is applied 1 to .the spokes. with the slots receiving the spoke ends, the wire spokes preferably fitting-snugly in the slots to hold the supporting ring centrally with reference to the frame while the ring and spokes are secured together as by soldering. Preferably longi' tudinal slots13 are extended a distance fromthe upper ends of the slots 12, the supporting. ring, after the spoke ends are received in the vertical slots, being iven a slight turn to bring the spoke ends into the longitudinal slots, such arrangement more securely holding the supporting ring in place preparatory to soldering.

As an additional means for centralizing and holding the supporting ring the spoke ends may be bent at right angles as indicated at 14, Fig. 3

With a supporting ring as described, the shade frame can be readily applied to and accurately and rigidly secured in the ordinary forms of holder. In Fig. 2 a holder H of the ordinary type is shown, the holder comprising the cylindrical wall 15 and the top 16 on which the neck 17 extends upwardly for receiving a support, such as an electric light socket. The wall 15 has the ordinary screws 18 threading radially therethrough. To apply my improved frame the screws 18 are withdrawn a sufiicient distance to permit entrance of the supporting ring 9 and when the screws are then turned inwardly they engage against the outer sides of the curved flared section 11 and draw the ring upwardly to bring the spokes against the lower edge of the holder H and the shade frame is then rigidly secured and accurately held. In shallower holders the upper edge of the supporting ring will be forced by the screws against the top 16 of the holder to cause the frame to hang properly. After the frame has been thus accu- 'rately secured in the holder an electric light bulb can be readily inserted through the Copies ofthisipatent may beobtain 'ifor cured;;to the skeleton frame to complete the shade. The marginal rings 5 and 6 can be circular, as shown, or elliptical, polygonal, or of other contour, depending upon the form of shade desired- I do not, of course, desire to be limitedto the exact construction and arrangement shown as modifications are no doubt possible which would still come within the scope edge for receiving the inner ends of the spokes, the upper section of said supporting ring being flared for cooperating with shade holder supporting screws.

2. In a lamp shade frame, the combination of a skeleton wire supporting structure forshade fabric, wire spokes at the upper end of said structure, a sheet metal supporting ring having slots extending from its lower edge for receiving the inner ends of the wire spokes whereby said ring may be centered relative to the structure preparatory to soldering of the ring to the spokes, the upper part of said ringrflaring to cooperate: with shade holder screws.

In witness whereofI hereunto subscribe my name this 8th day of December, A. D., 1916.
